package irmin-mem

The type for content-addressable backend stores. The 'a phantom type carries information about the store mutability.

The type for keys.

The type for raw values.

mem t k is true iff k is present in t.

find t k is Some v if k is associated to v in t and None is k is not present in t.

Write the contents of a value to the store. It's the responsibility of the content-addressable store to generate a consistent key.

Same as add but allows to specify the key directly. The backend might choose to discared that key and/or can be corrupt if the key scheme is not consistent.

Clear the store. This operation is expected to be slow.

merge t lifts the merge functions defined on contents values to contents key. The merge function will: (i) read the values associated with the given keys, (ii) use the merge function defined on values and (iii) write the resulting values into the store to get the resulting key. See Contents.S.merge.

If any of these operations fail, return `Conflict.

Key provides base functions for user-defined contents keys.

Val provides base functions for user-defined contents values.
